IMPROVEMENT IN SHOT-CARTRIDGES.

specification forming pim of Letters Patent No. 136.336, dated February 25, 1813.

To all whom it may concern:

Be it known that I, SETE W. PAINE, of lRochester,in the county of Monroe and in the State ot New York, have invented certain new and useful Improvements in Shot-Cartridges; and do hereby declare that the following is a full, clear, and exact description thereof, reierence being had to the accompanying drawing making a part of this specification, in

which- Figure 1 is a perspective viewot' my im- .proved cartridge-case from therear, as pre I periphery. 1

Letters of like name and kind refer to like parts in each of the figures. 1

rlhe design of my invention is to furnish a means whereby a charge of shot may be con. ned together for any desired length of time after leaving the muzzle of the. gun, and then.

released and permitted to pass' onward without obstruction from their envelope or case to which end said invention consists, princi pally, in combining with the staves or sections of a longitudinallyldivided cartridge-case al iconiining-cord'wound spirally upon or around the periphery of the same, substantially as and .for the purpose hereinafter specilied. It consists, further, in the construction of the sections or sides of the casing and in the means employed for locking the same'in relative 1ongitudinal positions, substantially vas and for the purpose hereinafter set forth. It consists, further, .in the construction of the apex and the means employed for combining the same with the sides, substantially as and fory the purpose hereinafter shown and described.

In the annexed drawing, A and A represent two semi-cylindrical sections,constructed of or from sheet metal, and corresponding in size and shape, so that when their edges are placed together they shall form a hollow'cy-linder partially or wholly inclosed at one end. In order that when combined the relative longitudinal' positions of the sections shall be insured, a notch, a, is formed with'n one edge of each, and

a corresponding projection, al', provided upon the contiguous edge of the opposite section, by the engagement of which the result above named is obtained. Within theopen end ot' A the casing is'placed an apex, B, constructed, preferably, ot papier-macho or other light material, in the form of a conical slug or ball, which apex at its base just ills the end of said casing, and is confined in place therein by means of a lip, a", attached to andv forming a part of each section, which extendsinward and engages with a corresponding recess, b, formed within the base of said apex. 4Within the lower end of the casing is placed a base-plate or follower, G, which rests upon the inward-turned ends of the sections, and practically closes the. opening within the end otf said casing.

As thus constructed the sections are com- `bined, the base-plate inserted, the space within said sections filled with shot, and the apex placed in position, after which the whole casing is irmly bound together by means of a ine cord, D, wound spirally around its periphery.

Upon leaving the gu-n the cord D will be unwound by the current of air caused by the rapid motion of the cartridge, after which the "casing will burst and its several parts fall to the ground, leaving the charge of shot free to perform its oliice.V

It will be seen that upon the length of the cord Wound around the casing will depend the amount of time consumed in unwinding the same and `liberating the charge of' shot, andv that in correspondence therewith will be the distance traversed by said .cartridge before bursting, so that, by increasingor diminishing the length of said cord, a longer or shorter range will be obtained.

In order that thesections may be liberated simultaneously at bothv ends, the cord is iirst wound around the' same at about the middle of their length fora space of about one-fourth of an inch, from thence is carried to' one end andwound inward toward said central portion, after reaching which said cord is carried to the opposite end and in alike manner wound inward again; the result of which method is that the 4ends of the casing are rst freed `from said cord'; and, lastly, the middle, by whichmeans neither end can Ispreadoutward in advance of the other, so as to change the direction ofthe cartridge, but all of said parts are confined in place until the last portion of the cord has been un wound.

In addition to closing the opening in the rear end ot' the casing, the base-plate furnishes a sufficient support for the charge at the instant that the sections ofthe casing are falling away at oblique angles.

Although the apexvis intended principally to perform the oiiice ot' a wad over the shot to-l guide the cartridge and to lessen the resistance oi'lered to its .passage through the air, -by constructing said apex of lead it may be used as a ball; and thus increase the capability and value of the cartridge. y' Having thus fully set forth the nature and merits of my'iuvel1tion\vhat I claim as new l 1. In combination with the shell o'fa longitudinally-divided cartridge-oase, a confining- I cord wound spirally upon or around the periphery ot' the same, substantially as and f o'r the purpose herein specified.` v

2. The sections A and A', when constructed as shown and provided with the notches a and projections a', substantially as and for thepurpose set forth. l Y

3. The apex B,"constructed as shown, provided with the recesses b and combined with the sections A' and A', Vprovided with the lips a", substantially as and for the purpose described.

In testimony that I-claim the foregoing I have hereunto set my hand this 4th day of February, 1873.
